[Morphology and clinical aspects of malignant mixed müllerian tumors of the corpus uteri].

Mixed muellerian tumours of the uterus are more common today than uterine leiomyosarcomata. There is a world wide increase in the incidence in the last few years. In the past 15 years we observed 20 mixed muellerian tumours of the uterine body. The patients are usually 10 years older than women with endometrial carcinoma or leiomyosarcoma of the uterus. Morphologically homologous and heterologous tumours must be differentiated. Characteristic is the marked polypoid growth. There is a close correlation between tumour stage and microscopic tumour grading. Tumours with high malignancy are usually in stage I or II. The prognosis correlates well with the grade and stage of the tumour, therefore the elaboration of a prognostic index is necessary. The survival rates are low. Mixed muellerian tumours are not at all or very little influenced by radiotherapy. The single or combined chemotherapies in use o date have not shown satisfactory success. As complete as possible surgical removal is therefore important. It cannot as yet be predicted whether our present combined treatment in stage III and stage IV by operation and post-operative combined chemotherapy with CYVADIC is liable to increase the survival rates.
